Where To Find It
Sheldon is listed in 1 habitat. Which creatures actually appear also depends on weather, time of day, and local phenomena, so a listed habitat is where to look rather than a guarantee.
Habitat |
|---|
Trait

Trait | Effect |
|---|---|
Tidal Heart | While in water terrain or after absorbing water, increases Water damage by 20% for 10s. |
Skills
Sheldon brings 2 combat skills and 1 innate skill into a fight. Power is the skill's published damage figure and Cost is what it draws from the resource bar.
Skill | Type | Power | Cost | Effect |
|---|---|---|---|---|
Torrent Slam | Combat | 47 | 20 | Strikes the target with a shell. If there’s a water environment nearby, activates puddles within the hit range to deal additional damage equal to 30% Might and increase Damage Amp by 15% for 20s. |
Hydro Roll | Combat | 83 | 20 | Continuously consumes stamina to roll forward and ram targets, dealing damage and restoring stamina over time. Creates a puddle when the roll ends. Stamina can be restored this way at most once every 3s. |
ATK | Innate | 6 | 0 | Wields the power of water to attack targets at close range. |
Wild Sheldon and the final evolution
Sheldon may appear during Echoback Landing Wild Surges. Its marked ordinary encounters also include a bouncing Sheldon and another with a Shelly group in front of a large boulder southwest of the Beachside Sandbars Bloom.
Evolution | Requirement |
|---|---|
From Shelly | Shelly reaches level 29. |
To Sherro | Sheldon reaches level 39 and the Young Omega Sherro quest unlock is complete. Check the evolution menu for its Wave Stone cost. |
To start Stars and the Knight, Twine with Susuta and go to the sand south of Beachside Sandbars in Echoback Landing. Dig at the shining spots and speak to the Shelly you uncover. Follow the quest through the Young Omega Sherro fight to unlock the final evolution.
Water setup and Homeland work
Use Hydro Roll to leave a puddle, then aim Torrent Slam so the puddle is inside its hit area. The resulting additional damage and Damage Amp buff make the puddle useful for the next attack. Water terrain or absorbing water also activates Tidal Heart.
